GameApi Builder is a 3d engine and node graph tool for creating trailers, game prototypes and even full games (with some caveats). With a library of 600 different nodes create full product via scripting language that contains the node graph, including node types and parameters used to tweak the end result. The product is designed for youngsters at the high school level and above. Let your game development story begin with our technology.
Here's a picture how the builder tool looks like, if you use it properly:

Then the game itself will look something like this, while you're editing it via ML nodes:

And run_window node gives you full game display for screenshots, final testing, videos etc:

Then once the game is ready, you can use html_run and save_deploy nodes to make a html5 distribution package:

And there you go, you're ready to see the result:

There you go, got a ALL OK and zip file saved to /home/terop/.gameapi_builder/Downloads/gameapi_deploy.zip...
uncompressing that to your hosting location directory will give you url to the display.php file and then browser should be able to open it. The game works in browser, but very very slowly. The reason is that pthreads and brotli are disabled, so you'll need to practise your web server maintainance skills and setup SharedArrayBuffer support (and domain name and https is required) and brotli support. These enable 8 cpus and compression.
